摘要
Abstract
Aiming at the problem that current license plate image detection inaccuracy and inclination angle error is big,tilt correction of vehicle license plate approach was proposed based on Radon transformation. License plate was located in vehicle license image; then license plate image was used for edge detection and Radon transformation;according to Radon parameters,horizontal and vertical tilt angle were detected;vehicle license image was corrected using bilinear interpolation. Experiment results showed that this method could verify the correctness of the approach,which could realize the correction of all kinds of tilts.关键词
